The HUNOR RANDAM (RAdNano Dosimeter Astronaut Module) project aims to monitor crew radiation exposure and environmental conditions during the Ax-4 mission. The miniaturized devices designed for everyday personal wear will track radiation levels, temperature, humidity, air pressure, carbon dioxide levels, light intensity, and magnetic fields. Measurement of radiation levels are important for crew health and safety. Insights gained could improve radiation protection strategies for future spaceflight and advance Earth-based technologies for radiation monitoring and environmental sensing.

Acceleration environment of the Ax-4 crewed spaceflight measured by wearable RadNano Infinity Astronaut Dosimeters
- Active-period mean accelerations were 0.014 g and 0.013 g for two astronauts.
- Astronaut motion produced accelerations far above the nominal microgravity level.
- Jensen–Shannon distances showed broadly similar acceleration distributions.
- Overlapping 5-minute moving RMS windows characterised astronaut movement intensity.
